Answer:
Wind is the horizontal movement of air. All wind is caused by the uneven heating of Earth's surface, which sets convection currents in motion. Convection currents on a large scale cause global winds; convection currents on a small scale cause local winds.
Explanation:
Answer:
about 29% ( I'm not sure tho I'm sorry)
Without those parts, the cell wouldnt be able to perform its basic function and thus die
Answer:
The option c is partly correct.
Explanation:
None of the statements is completely accurate because:
a. Saurischian dinosaurs include theropod and sauropod dinosaurs, and their common ancestors. Ornithischians comprise neornithischians (ornithopods and ceratopsians), thyreophorans (ankylosaurs and stegosaurs) and heterdontosaurids.
b. Capability to fly has only been documented in fossils belonging to Saurischia (where the birds are also classified in). Feathers, on the other hand, do appear in the two clades. Feathers, however, are not a trait exclusively associated to flight.
c. This is a correct comparison between ornithischians and saurischians in the sense that the attributes do belong to these clades, but when comparing animals there most be a comparison that reflects a pattern. Ornithischians have leaf shaped teeth suited to eat plant material, whereas saurischians have teeth for a carnivore and herbivore diet.
d. Sauropods are saurischians and they evolved herbivory from a meat-eater ancestor.
Answer:
- The Island population likely has fewer alleles-that is versions of genes-than the mainland population.
A- Agree <u>B- Disagree</u>
- Genetic drift is more pronounced in the island population than in the mainland population in these first few generations
A- Agree <u>B- Disagree</u>
- Some harmful traits may have become more common in the island population than in the mainland population
<u>A- Agree</u>- B- Disagree
- Biologist observed genetic drift but not evolution
<u>A- Agree</u> B- Disagree
Explanation:
If there was genetic drift, then allele frequency either increased or decreased by chance, irrespective of natural selection that is irrespective to weather those alleles helped individuals survive in the island environment. In molecular genetic data, there are statistical signature in the population variation that indicate weather selection or other processes occurred.
